Research

Dr. Webber's research is focused on high energy cosmic ray physics. He is
directly involved with cosmic ray experiments on both the Pioneer 10 and
Voyager 1 & 2 spacecraft. These spacecraft are the first manmade objects to
leave the solar system. Dr. Webber has a wide range of interests, including
studies of cosmic rays in the heliosphere using the Pioneer and Voyager
spacecraft, H and He isotope studies and anti-proton measurements - I MAX
balloon experiment, measurements of nuclear cross sections using liquid H
targets at the SATURNE accelerator in France for Big Bang nucleosynthesis,
Monte-Carlo simulations of cosmic ray nucleons and electrons in the Milky Way,
studies of cosmic ray elemental and isotopic composition on Voyager, the
Gamma-Ray Distribution in the Milky Way, and Gamma Ray Bursts. Dr. Webber is
retired, but he remains a prolific researcher and continues to publish several
scientific papers per year.

Currently Dr. Webber is working with Voyager I data in a search for the "solar
shock", where the sun's solar wind slams into the interstellar gas between the
stars.
